On high resolution head-related transfer function measurements: An efficient sampling scheme

On High-Resolution Head-Related Transfer Function Measurements

This paper deals with two important questions associated with HRTF measurement: 1) “what is the required angular resolution?,” and 2) “what is the most suitable sampling scheme?.” The paper shows that a well-defined finite number of spherical harmonics can capture the head-related transfer function (HRTF) spatial variations in sufficient detail, which is defined as the HRTF spatial dimensionali...

A Database of Repeated Head-related Transfer Function Measurements

This paper describes a new HRTF collection, measured at the Music and Audio Research Laboratory (MARL), at NYU. This collection of 40 datasets, consists of repeated HRTF measurements on 4 subjects (10 HRTF sets per subject). Analysis of the data offers an understanding of the expected degree of variation in HRTF sets, which, when supported by subjective evaluation, can provide deeper insight fo...

System for High Speed Measurement of Head-Related Transfer Function

A High Resolution and Full-Spherical Head-Related Transfer Function Database for Different Head-Above-Torso Orientations

Head-related transfer functions (HRTFs) were acoustically measured and numerically simulated for the FABIAN head and torso simulator on a full-spherical and high resolution sampling grid. Moreover, HRTFs were acquired for 11 horizontal head-above-torso orientations, covering the typical range of motion of ±50 , making it possible to account for head movements of the listeners in dynamic binaura...

Analysis of the Spectral Variations in Repeated Head-related Transfer Function Measurements

This paper discusses the range of spectral variations between HRTF sets measured on the same subjects. The analysis is done in a corpus of 40 HRTF datasets of 4 subjects (10 datasets per subject). Variations are observed as a function of frequency, distance of the ears to the sound source (ipsilateral or contralateral), and location. Assessments of the spatial quality of all datasets were made ...
